Usage:

• Use for Henry® air barrier, roofing and water-proofing systems as external joint sealant
• For self-adhered air barriers, it builds an envelope sealant
• In applications for construction that are above-grade, it provides an alternative to moisture cure silicone and urethanes
• Suitable for use in construction joints with a maximum of 1 inch (25 mm) width susceptible to vigorous joint movement of ± 35% ApplicationSurface Prep: Ensure joints are sound, uniform, free from defects and foreign materials, and smooth. Ensure joints are free of frost, dry, clean, and free of all contaminants, such as coatings, sealers or curing compounds. Before use, test sealant on every different substrate by applying a bead and allowing it to cure thoroughly. Pull one end of the bead to test adhesive strength. Apply: Make a cut on nozzle to desired bead size and puncture inner seal. Apply sealant ahead of nozzle at a 45° angle. Joint width should be at least 4 times the anticipated movement. Sealant depth should be equal to the width in joints up to 1⁄2 inch (13 mm) wide, but not less than 1⁄4 inch (6 mm). Maintain a depth at 1⁄2 inch (13 mm) in joints wider than 1⁄2 inch (13 mm). For installation, the maximum joint width is 1 inch (25mm). Tooling is required to eliminate air bubbles and to aid contact with the substrate in horizontal and vertical joints.
